A guide to sources of information on obesity

More on the extent

Here is what the World Obesity Organisation says:

The epidemic of obesity is now recognized as one of the most important public health problems facing the world today. Tragically, adult obesity is more common globally than under-nutrition. According to the World Health Organisation (2014) their are around 2 billion adults overweight, of those 670 million are considered to be affected by obesity (BMI ≥30 kg/m²) and 98 million severely affected by obesity (BMI ≥35 kg/m²).  If current trends continues it is estimated that 2.7 billion adults will be overweight, over 1 billion affected by obesity and 177 million adults severely affected by obesity by 2025. 

We estimate that over 200 million school-age children are overweight, making this generation the first predicted to have a shorter lifespan than their parents.
